S32M2 Smart Controller featuring Sensorless FOC algorithm for eVTOL systems

Description - 202503S1

The high-performance S32M2 microcontroller is well-suited for supporting PMSM (Permanent Magnet Synchronous Motor) and BLDC (Brushless DC) solutions in eVTOL (electric Vertical Take-Off and Landing) applications.

At the core of the S32M2 is the Sensorless FOC (Field-Oriented Control) algorithm, an advanced motor control technology that eliminates the need for physical position sensors. By analyzing real-time voltage and current signals, the algorithm precisely determines motor speed and position, delivering smooth and efficient motor control. This technology enhances system precision and improving overall reliability.

Designed with space efficiency in mind, the controller minimizes peripheral components, allowing seamless integration into compact drone architectures. This solution offers a robust platform for implementing PMSM and BLDC motor control in drone and eVTOL systems. Its processing power, integrated motor control capabilities, safety features, and communication options make it an effective choice for ensuring efficient and reliable operation.
